OK, I know absolutly nothing about electronics but I'm trying to learn some basic electronics/circuits by myself. So, I got a breadboard, a book with some basic electronic info and projects, some components and a variable power supply that has 3V, 6V,9V and 12V. My question is how do I connect the power supply to the breadboard. The breadboard I got was one that has 3220 holes and is mounted on to a black backing plate that has 4 connectors labled Va, Vb, Vc and Ground. Do I connect the red and black wires from the power supply to the red and black connectors on the backing plate? Would I use the matching red and black connectors from the breadboard? And where should I put them? Va, Vb? What do I do about the ground? From there how would I power the circuits so that my led will glow like it says it should in the book. I did search the internet for breadboard basics, but couldn't seem to find any info on how the power supply should be hooked up. Any and all advice would be appreciated.
